This June, members of the lab attended Phononics 2019: the 5th International Conference on Phononic Crystals/Metamaterials, Phonon Transport, and Topological Phononics. Several students presented ...

When a carrier collides with a phonon, both energy and momentum are conserved. Energy and momentum conservation impose constraints on the maximum wave vector change and, therefore, on which phonons ...
